Product Information Rechargeable Wireless Mouse Bluetooth Lightweight Slim Design Portable NEW Blue Rechargeable Wireless Bluetooth Mouse Based on customer feedback of last several months, we made some improvements to make the mouse better: Solution about Connection. There were 5% customers met them. Because No Bluetooth Chip can match more than 1000 Bluetooth drives, after lots of tests we chose the best Bluetooth 3.0 Chip - AIROHA AB1129F. The issues can be reduced from 5% to ≤1%. If any issue, automatically reinstall a new Bluetooth drive can solve it at most times. Solution about Battery. We adjusted the structure to keep the battery system stable, to prevent it damaged during transport. And we upgraded the battery capacity from 600 to 750 mAh, it can run 2 weeks with 8 hours every day. Solution about Sleep & Wakeup. We spent much time on the balance between power save and fast wakeup. The mouse will fall asleep after 10 minutes no-operation, when you use it, click any button and waiting 1-3 seconds, it will wake up. If you won't use it for a long time, we suggest you to turn the switch to off for saving battery.Besides, we also modified the mice edge for more comfortable feeling, changed the scroll wheel for complete noiseless... We always do our best to improve customer experience.
